Is corrosion a problem in your house too?
Corrosion of metal drinking water installations is not caused by a chemical water composition only. Corrosion is favoured by low-quality raw materials, foreign particles (sand, rust, hemp etc.), incorrect mounting and water stagnation (for. ex., no water consumption during vacations, in summer cottages, empty flats). Corrosion is not a danger only. It is even necessary when an oxidizing protective coating prevents further corrosion. In this case we deal with passivation. Only point corrosion is dangerous for water pipes made of metals.
WFC offers the best problem solution:
* WFC filter as a basic requirement
In accordance with the state of technology and DIN 50930 a DVGW-tested protective filter is required in each house. Back-wash filters or replacement filters have advantages because the water feed is not interrupted when cartridges are exchanged or cleaned. BWT offers the corresponding filters to meet different demands. They range from ordinary replacement filters to fully automatic back-wash filters.
* Dosing additives: corrosion control according to DIN 50930
Corrosion protection additives must be chosen in compliance with the material available and individual water quality. For example, if the content of carbonic acid is very high or pH- values are too low alkaline additives should be used.
Alongside the required mineral substances BWT offers the dosing equipment, for ex., dosing unit Bewados. The equipment is DVGW-tested. All the requirements for drinking water are satisfied. Only additives of food quality are used.
* QA total-plus: protection from rust and lime
Brown-red colour or brown stripes in your bathroom are the first signals of corrosion in water pipes caused by aggressive water. One more problem can be added here: the boilers encrusted with lime and the spray jets becoming thinner and thinner from day to day indicate to water hardness. When a unique AQA total-plus unit is used expensive sanitation is not necessary.
The solution of the problem: AQA total-plus. The innovative 2-phases IQ-technology ensures effective protection from lime and corrosion in house water installation, boilers, zinc-plated pipes, iron and copper pipes. AQA total-plus refers to DVGW-tested AQA total XP 1500 and 2500 systems. AQA total-plus ensures additional protection from rust. More than 50.000 units AQA total-plus are already installed in Europe.
